Possible problem with long parameters for NEEDS.

[Galenmacil]

After seeing several patches getting applied even though their NEEDS is not met, I have come to the following conclusion:

Long parameters are not processed correctly by NEEDS.

Prime example of this, verifiable on several mod that use similar syntax:

@part[aeroPartxx]:NEEDS[FerramAerospaceResearch]:BEFORE[FerramAerospaceResearch]
{
@minimum_drag = 0
@maximum_drag = 0
@angularDrag = 0
!MODULE[ModuleLiftingSurface] {}
}

Even though FerramAerospaceResearch IS NOT available, the patch still gets applied.

This runs perfectly fine here.
"[ModuleManager] Deleting Node in file /test subnode: @part[aeroPartxx]:NEEDS[FerramAerospaceResearch]:BEFORE[FerramAerospaceResearch] as it can't satisfy its NEEDS"

Since you do not provide a full log I can not identify your actual problem.
